San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

Steps To Make A Rat Trap
Catching a rat is a pretty easy job if you have the right tools. Without a doubt, rat traps are one of the oldest and simplest methods that could be used when catching these nasty rodents.
Homemade traps are very effective for catching rats, and making them is really simple. There are infinite options. Below, we will explain all the steps to make a rat trap.
But before doing that, here are some points that you should take into account:- Evaluate your materials: depending on the materials you have, you can make different types of traps. This time, we will make a homemade trap whose main materials are a plastic bottle, newspaper, cardboard, and rat glue.
- Define specific points: there are places in your home that can be very attractive to rats, especially those that provide food or shelter: the kitchen, dining room, or holes in the walls.
- Building the trap is really simple: you can cover the surface on which you will place the trap with newspaper, and you can place a piece of cardboard on which you will put rat glue, leaving a space in the middle to place the bait, -which could be a piece of cheese-. This bait will attract the rat and it will get stuck.
Sounds pretty easy, right? But...
What Happens If The Rat Evades Your Traps?
You may be dealing with a rat that has learned to survive in the most dangerous environments, so they will completely avoid all those things that could be a threat. In this case, you must add poison to the list of materials.
If you use the same technique, it is likely the rats will evade it again. So change the strategy; you can keep the traps with rat glue but poison the food this time.
It is important to note that poisons may have a delay in taking effect, so it is important to locate the rat after it ingested the poison. If not, it might die in places that are difficult to access.
